UNITED sTATEXs PATENT: OFFICE. NN f THOMAS J. DINTON, OF PROVIDENCE, RHODE ISLAND. i

Specification` of Letters Patent No.

To all 'whom it may concern:

Be it known that I, THOMAS J. LINTON, of the city and county of Providence, in the State of Rhode Island and Providence Plantations, have invented a new and useful Improvement in the Manufacture of Mountings for Precious Stones and other Articles of Jewelry which are to be Mounted; and I do hereby declare that the following is a full and exact description of my improvement, reference being had to the accompanying drawings. i

Mountings for precious stones, have before my improvement been made as follows: A bar of gold or other metal, of the requisite length, width and thickness is so bent that the ends are brought together and soldered, forming the border as in Figure l. Another bar of metal, suitable for the setting, is also prepared by bending and soldering, in the shape as represented in Fig. 2. The border and the setting are then, by the workman, soldered together, and the upper edge of the setting turned inward by a burnisher, forming a beveled edge to receive and secure the .stone to be mounted. These several processes are slow and expensive, requiring many hands, and a Variety of implements.

My improvement consists in making the border, the setting, and the beveled edge of the setting, from a single piece of metal, and at one operation. This is done by means of a die, cut in the form required for the shape and size of the stone to be mounted, on which the sheet of metal is placed, and the mounting is struck into the required forms MOUNTING PRECIOUS STONES, 8m.
